Abstract: Currently, there is an ever-increasing demand for organic food from consumers who are convinced that it is healthier and more nutritious. The purpose of our research was to carry out an evaluation of the nutritional and sensory characteristics of organic and conventional hazelnuts of Tonda Gentile Romana cv. To this end, volatile composition, total phenolics, antioxidant capacity, and sensory profile of organic and conventional hazelnuts were identified. In comparison to conventional hazelnuts, organic hazelnuts had a greater amount of total phenols and antioxidants. Furthermore, organic hazelnuts had a different sensory profile, with more crunchiness (6.722 vs. 4.056 for raw and 8.389 vs. 4.667 for roasted) and sweetness (7.667 vs. 4.867 for raw and 7.089 vs. 3.889 for roasted), accompanied by distinct hazelnut, almond, walnut, popcorn, coffee, and roasty notes, present in much higher amounts than conventional hazelnuts. One of our key findings is that organic hazelnuts have a higher nutritional value due to their higher antioxidant capacity. Promoting organic hazelnuts helps to encourage consumers to use these products, which have a high nutritional value, thus contributing to public health.
